[Heso no Gomaabura (Hekoman)] Let's Choo-Choo! (Blue Archive) [COHQ]

A shy teacher and two energetic schoolgirls engage in a teasing, power‑play threesome that blends innocent curiosity with dominant control. The story follows Sensei Hikari as she guides the shy boy through a series of playful, intimate encounters, while Nozomi eagerly pushes boundaries and revels in her role as the commanding partner. With a mix of gentle coaxing, surprising intensity, and the thrill of a forbidden dynamic, the album offers a vivid, erotic narrative that keeps the reader hooked from start to finish.
